8.2.2 Multiple location

<!attlist multloc ordering (ordered | noorder) noorder set (set | notset) notset aggloc (aggloc | agglink | nagg) nagg>

ordering: Is ordering of locations significant?
set: Make multiple a set by ignoring duplicates
aggloc: Are multiple locations an aggregate?

8.2.3 Span location

<!attlist spanloc spanloc (spanloc | spanlink | nspan) nspan limsort (limsort | nlimsort) nlimsort>

spanloc: Do multiple locations comprise a span?; Constraint: spanlink requires hyperlinks module
limsort: Are limits sorted with span start first?

8.3.2.1 Named location address

<!element nameloc - O (nmlist | nmquery)*>

<!attlist nameloc HyTime NAME nameloc id ID #REQUIRED -- multloc attributes -- -- spanloc attributes -- -- common attributes -->

#CONTENT: Assigns a local ID to one or more named objects; Constraint: name list derived from content elements.

8.3.2.2 Name list specification

<!element nmlist - O (#PCDATA)>

<!attlist nmlist HyTime NAME nmlist nametype (entity | element | unified) #REQUIRED obnames (obnames | nobnames) #REQUIRED docorsub ENTITY #IMPLIED dtdorlpd NAMES #IMPLIED -- common attributes -->

#CONTENT: List of local or external ID or entity names; lextype(NAMES)
nametype: Entity names or IDs of elements
obnames: Objects treated as names?
docorsub: SGML document or subdoc whose prolog declares entities or elements used in name list; initially the document in which this occurs.; Default: no change
dtdorlpd: Active DTD or LPDs for SGML document entity. Base DTD if unspecified and docorsub changed; no change if unspecified and docorsub unchanged.; lextype(DTD|LPD+); Default: unchanged or base

8.4.1 Data location address

<!element dataloc - O (dimlist*)>

#CONTENT: Locates string and token data objects in data; Constraint: dimlists are concatenated into one list
quantum: Data quantum: bit combination or token
catsrc: Concatenate multiple source objects into a single object before applying dimlist to it
catres: Concatenate results of applying dimlist, in the order of the dimlist

8.4.2.3 Tree combination

<!attlist treecom treecom (treecom | ntreecom) ntreecom>

treecom: Combine multiple source trees

8.4.2.4 Tree location address

<!element treeloc - O (marklist*)>

<!attlist treeloc HyTime NAME treeloc id ID #REQUIRED -- overrun attributes -- -- treecom attributes -- -- locsrc attributes -- -- multloc attributes -- -- spanloc attributes -- -- common attributes -->

#CONTENT: Locates nodes in a tree by classical method; Constraint: marklists are merged into a single list that contains 1st markers only; implied marker2 is 1

8.4.2.5 Path location address

<!element pathloc - O (dimlist*)>

<!attlist pathloc HyTime NAME pathloc id ID #REQUIRED -- overrun attributes -- -- treecom attributes -- -- locsrc attributes -- -- multloc attributes -- -- spanloc attributes -- -- common attributes -->

#CONTENT: Locates nodes in a tree viewed as a path list; Constraint: dimlists are merged into a single list that resolves to pairs of dimspecs

8.4.2.6 List location address

<!element listloc - O (dimlist*)>

<!attlist listloc HyTime NAME listloc id ID #REQUIRED -- overrun attributes -- -- locsrc attributes -- -- multloc attributes -- -- spanloc attributes -- -- common attributes -->

#CONTENT: Locates nodes in a node list viewed as a list

8.4.2.7 Relative location address

<!element relloc - O (dimlist*)>

#CONTENT: Locates nodes in a tree relative to a starting node; Constraint: dimlists are merged into a single list that resolves to pairs of dimspecs
root: Root of tree; Constraint: 1 per starting node or 1 for all; Default: document root of each starting node
relation: Relationship to starting node; Constraint: des requires "pathloc" option

8.5.1 Property location address

<!element proploc - O (qpn | #PCDATA)>

<!attlist proploc HyTime NAME proploc id ID #REQUIRED joint (joint | several) several apropsrc (apropsrc | solesrc) solesrc notprop (error | empty | ignore) ignore -- locsrc attributes -- -- multloc attributes -- -- common attributes -->

#CONTENT: Locates attribute or other property; lextype(QPN)
joint: Joint property of relationship of members of multiple locsrc?
apropsrc: Use additional property source?
notprop: If not a property of locsrc or apropsrc?

8.5.2 Notation-specific location address

<!element notloc - O (%HyBrid;)*>

<!attlist notloc HyTime NAME notloc id ID #REQUIRED -- query attributes -- -- function attributes -- -- multloc attributes -- -- common attributes -->

#CONTENT: Locates an arbitrary portion of data in terms of its data content notation (e.g., internal label, 3rd polygon in graphics notation). Query that returns object, rather than address

8.5.3 Bibliographic location address

<!element bibloc - O (%HyBrid;)*>

<!attlist bibloc HyTime NAME bibloc id ID #REQUIRED -- query attributes -- -- function attributes -- -- common attributes -->

#CONTENT: Textual bibliographic reference to real object; Represents an address that is processable only as data

8.7.1 Query attributes

<!attlist query qdomain IDREFS #IMPLIED qcontext IDREF #IMPLIED>

qdomain: Domain of the query; For some query notations, domain is inherent and this attribute will be ignored.; Constraint: No HyTime reftype constraints; Default: inherent in query
qcontext: Semantic and parsing context for domain; reftype(HyBrid); Default: inherent in query

8.7.2 Name list query

<!element nmquery O O (%HyBrid;)*>

<!attlist nmquery HyTime NAME nmquery -- query attributes -- -- function attributes -- -- common attributes -->
